Black Leg Style

A lot of people call it his signature technique but I can only remember him using it a few times, first to finish off kuroobi, then using the diable jambe version against a pacifista, a beast pirate, and against queen with zoro

I feel like i remember him using it a bunch early on but the only times i can find him using it are the first one against the sea cow and the diable jambe one against judge. Does anyone remember him using it other times? I feel like im losing my mind

Is it named "Black leg style" in a data book or is it just named that by the wiki editors? If the latter is true shouldn't it be named red leg style?

Imagine if sanji had the mera mera no mi so he can turn into fire so he could use diable Jamie on all parts of the body and even create fire fists like ace and sabo. He would also be a good pika pika no mi user at teleport with the light and then attack with diable Jambe

Sanji is well written character with emotion,sad backstory another sad backstory and yet he made it out happy. But today i am here to discuss on how Sanji is being robbed by Oda. First off Sanji was capable swordsman trained by Germa 66 and he did so with profiency and skill and we only saw this once in water 7 against Wanze but sanji refuses to use his skills in battle for the sake of his hands which is just ridiculous.

Everybody knows Sanji, martial arts black leg and his move Diable Jambe. In the pre time skip era whilst fighting against Jabra and Oars he spins really fast to burn his feet. But post time skip, (perfect example is him fighting against Luffy.) he just puts his legs up and it just burns. I don't have the mangas after the timeskip so I dont know if they explain it in the manga. And if they tell it in the anime, i dont remember it(probably wasnt paying much attention.) How does he do this? I dunno and if you know pls tell me.
